Windows is itself a complex operating system. Checking the processes that are actively and continuously accessing your hard drive and processor is very important, especially to detect suspicious activities or even a badly installed software.
Let’s say a program is idle or not running, logically it should not be using much resources from your computer or may not even using any resources from your computer. If it does, then you should take extra care to learn more about the process.
But how to know that specific program is active or inactive?
